it would use all the memory, it means 2 gig since its on xfire every gpu has its own memory it would handle huge texture better than single
not coz its 2 gb the rest 2 gb wont get used, xfire would use all

So they're each using 1gb then right?... and if so... it means that someone who buys 2x 6950 1gb only uses 1gb in CFx correct?

It means that each GPU will use the amount of RAM the card with the least amount of RAM has one it. Two 1gb cards will use 1gb per GPU. If you have something like a 512mb 4870 and a 1gb 4870, each gpu will use 512mb. If you have say a 1.5gb card and a 3gb card, both GPUs will use 1.5gb of RAM. If you have two 3gb cards, the GPUs will use 3gb apeice.

So to answer your question, your 2gb 6950 cards are using 2gb of vRAM per GPU.

You say both my cards can use 2gb of memory in a CFx config... Doesn't this add up to 4gb TOTAL then ???

Meaning... in the future... when games use more than 2gb for textures and whatnot... will my 2x 6950 2gb cards in CFx be able to use more than 2gb TOTAL... or they will be capped @ 2gb even though there's 2gb on each card ?
